Granted: 1982-06-08
Abstract: Abstract:     The invention relates to a semiconductor laser device having a shortened oscillation wave length.  This semi-conductor laser device has a doublehetero structure and comprises a semiconductor substrate composed of a GaAsP crystal, a first cladding layer formed on the substrate and composed of a GaA?AsP crystal of one conducting type, an active layer formed on the first cladding layer and com-posed of a GaInAsP crystal, and a second cladding layer formed on the active layer and composed of a GaA?AsP crystal of the conducting type reverse to that of the first cladd-ing layer.  Naturally, the cladding layers disposed on both sides of the active layer have a lower refractivity and a larger band gap than in the active layer.  The semicon-ductor laser device can be used in optical information processing devices, video discs and the like as small, high-efficiency light sources.

Abstract: APPARATUS AND METHOD FOR CORRECTING     IMPERFECTION IN A POLYGON  USED FOR LASER SCANNING                  Abstract of the Disclosure An electro-optical light scanning system using a modulated laser illumination source directed upon a multifaceted rotating polygonal mirror or polygon.  The mirrored facets reflect the impinging light toward a moving photoreceptor and forms a raster of scan lines as the photoreceptor moves.  The system incorporates sensing optics and closed loop electronics for correcting inac-curacies in the position of the reflected light resulting from deflects in the angular relationship between the plane of the facets and that of the rotating axis of the polygon.  Such cor-rection is accomplished through use of selectively located re-flective and transparent surfaces wherein location of the imping-ing light may be determined.

Abstract: OSCILLATING KNIFE CUTTING APPARATUS       Abstract of the Disclosure An oscillating knife cutting apparatus preferably for use on a row crop harvesting unit of a forage harvester to sever crop material from its standing position in a field as it is delivered into the harvester.  The apparatus comprises a main support with a main pair of knives fixed thereon, a bearing fixed to said main support, a shaft rotatably mounted in said bearing, and a second-ary support with a knife fixed thereto.  The secondary support is mounted on said shaft for oscillatory movement therewith relative to said main support.  The secondary knife is disposed between the pair of main knives and is used to sever material disposed between the secondary knife and each of the main knives.  The secondary knife is adjustably mounted for movement toward the plane defined by the main knives by adjustment of a member thread-ably mounted longitudinally of the shaft whereby rotation of the threaded member frictionally engages a clamp mounting the second-ary support on the shaft.  Also to compensate for uneven wear of the knives, one end of the secondary knife is bendable toward the plane defined by the main knives through rotation of a screw threadably mounted in the secondary support.

Abstract: CHILD-RESISTANT CLOSURE AND CONTAINER ASSEMBLY INCLUDING IMPROVED OUTER CAP                  ABSTRACT         A safety closure and container assembly including a container and a closure comprising outer and inner caps which may be attached to the container by conventional capping machines.  In first, second, third and fourth embodiments of the invention, the inner cap is formed with a circular dome-shaped top panel with a skirt portion pro-jecting axially therefrom,  The projecting skirt portion is threaded on its interior surface for engagement with a conventionally threaded con-tainer finish.  A plurality of upwardly extend-ing and spaced apart drive members are integrally molded with the periphery of the top panel. plurality of ramped ratchet lugs also extend upwardly from the upper surface of the top panel. The outer cap has a circular end wall with an axially projecting second skirt portion.  In the fourth embodiment of the outer cap, the end wall has an annular portion having a smaller thickness than the remainder of the end wall.  The second skirt portion loosely encompasses the first skirt portion to allow relative rotary movement between the inner and outer caps.  Integrally formed on the interior of the end wall are a plurality of inclined ramped ratchet lugs.  In the fourth-embodiment of the outer cap a plurality of spaced, sloping ratchet projections are integrally formed on the interior of the end wall.  The re-duced thickness of the annular portion and the ratchet projections facilitate slippage of the outer cap over the inner cap to prevent removal of the closure unless the inner and outer caps are first aligned and then the outer cap is pressed down to overcome the bias of the dome-shaped top panel.  A plurality of drive lugs extend downwardly from the periphery of the interior of the end wall.
